I can definitely see that!
Yet, I don’t hold the writers or Disney fully responsible for not including Santino or Hans in stuff. I mostly blame the fans and the viewers of Frozen who have this deep irrational hatred of Hans. I bet JLee and Santino weren’t expecting people to react so harshly towards Hans and I honestly believe Santino when he said JLee ("The writers who are great friends as well…") had an idea to redeem Hans. However, I did notice after he said that he uttered, “I’m not going to hold by breath though,” and the reason I think he uttered that is because of the unexpected and blatant hatred towards Hans so the writers might not be able to go through it.
JLee said in a couple interviews that a lot fans misinterpreted characters and some of the events that transpired in the film and “there’s a discourse going on because of it.” She’s hesitant to further progress the characters and the Frozen story in the way she original intended because she doesn’t want to mess with fans’ head-canons/views/imaginations.
People do view Hans as Satan and I honestly don’t get it! When people say Hans is the worst/evilest Disney villain ever I really just want to smack them hard across the face because in all honesty he’s not even close. I don’t think that it was JLee’s intention to make Hans this hated of a character and I do think she is still protective of him in some ways. JLee was pretty quick to dispel that one rumor about Hans being executed on her Twitter page, which is shocking considering she is so against responding to Frozen fans’ questions/head-canons/views in order to not disturb their imaginations. She obviously doesn’t want people thinking or head-canoning that Hans has been executed, which kind of proves that she still cares about Hans and his future.
Poor Santino is caught in the middle of all this mess and it’s not right that the majority of the Frozen fandom and audience are essentially pushing him and his character out of the franchise simply because they don’t get Hans. Lasseter better give JLee the green light to redeem Hans so Santino can give a big fat middle finger to all those Hans haters out there because he and Hans deserve that recognition.
